National Institute of Mental Health Funds Research Study Linking Sleep and Emotional Regulation to Suicidal Ideation

A joint team of researchers from the Austen Riggs Center, Long Island University, and Rutgers University hypothesize that for certain psychiatric patients, disturbed sleep negatively impacts daily interactions with others, and those negative interactions can in turn increase the likelihood of suicidal thoughts and behaviors.

Katie Lewis, PhD is the Research Psychologist at the Austen Riggs Center, Stockbridge, MA.Stockbridge, MA – October 22, 2019 –Utilizing smartphone technology, researchers Nicole Cain, PhD (Rutgers University), Katie Lewis, PhD (Austen Riggs Center), and Kevin Meehan, PhD (Long Island University) will monitor 105 adult psychiatric patients over a period of two weeks as part of a longer National Institute of Mental Health (NIMH) funded study to determine if disrupted sleep leads to higher instances of suicidal thoughts and impulses.

The study comes at a time when suicide is the tenth leading cause of death in America, according to the American Foundation for Suicide Prevention. The group also reported that in 2017 some 47,173 Americans died by suicide, with an estimated 1,400,000 suicide attempts.

While previous studies on patients diagnosed with sleep and circadian rhythm disorders have examined the relationship between disturbed sleep and suicide, this project represents the first of its kind to focus on sleep disruption, interpersonal relationships, and suicidal thoughts as experienced in the moment by patients with chronic and severe mental illness. 

“In suicide research, the majority of studies focus on risk and protective factors for suicide, the broad things that are familiar to most people like depression, hopelessness, and impulsivity,” Lewis said. “This work focuses on who might be at risk on more of a momentary level, as well as how sources of risk might interact with personality factors to increase the immediacy of danger for a particular individual.”

“Traditionally research has overly relied on what participants remember—how they felt, how they acted, how they slept the night before—and yet we know that memories of our feeling and behaviors can be faulty,” Meehan said. “This project will use technology to capture more real-time assessments—including ratings throughout the day that patients enter in their smartphones of feelings and events, and monitoring through the night while wearing a sleep tracking watch—which allows us to model these emotional events as they unfold over time,” he added.

“Poor sleep quality disrupts our ability to regulate our emotions, thoughts, and behaviors, which can then lead to an increase in suicidal thoughts and behaviors” Cain said. “This study will allow us to investigate the cumulative effects of sleep disruption on momentary risk for suicide.”

The overall study, which begins this year and will conclude in 2021, involves patients at the Rutgers University community-based psychological services center; the LIU Brooklyn counseling center; and the Austen Riggs Center, which is a long-term residential treatment facility.

Research reported in this release was supported by the NIMH, which is a part of the National Institutes of Health, under award number RF1MH120840. The NIMH provided $398,981 for the project, which represents 100 percent of the study being financed with federal money.
